1、res目錄下新建anim資料夾，在anim資料夾下新建xml檔案

slide_right_in.xml(右邊進入動畫)

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
    <translate
        android:duration="300"
        android:fromXDelta="100.0%p"
        android:toXDelta="0.0" />
</set
 
>

slide_right_out.xml(右邊退出動畫)

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
    <translate
        android:duration="300"
        android:fromXDelta="0.0"
        android:toXDelta="100.0%p" />
</set>

2、程式碼：

//進入動畫
public class
 
 MainActivity extends AppCompatActivity{

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        findViewById(R.id.btn).setOnClickListener(new View.OnClickListener() {
            @Override
 

            public void onClick(View v) {
                //進入動畫
                ActivityOptionsCompat optionsCompat = ActivityOptionsCompat.makeCustomAnimation(MainActivity.this,R.anim.slide_right_in,0);
                ActivityCompat.startActivity(MainActivity.this, new Intent(MainActivity.this, TestActivity.class), optionsCompat.toBundle());
            }
        });
    }

}

//退出動畫
public class TestActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_test);
    }

    @Override
    public void onBackPressed() {
        super.onBackPressed();
        //退出動畫
        overridePendingTransition(0, R.anim.slide_right_out);
    }
}

也可以把進入、退出動畫寫在一起

public static void rightEnterAndRightExit(Context context, Intent intent) {
        ActivityOptionsCompat optionsCompat = ActivityOptionsCompat.makeCustomAnimation(context,
                R.anim.slide_right_in, R.anim.slide_right_out);
        ActivityCompat.startActivity(context, intent, optionsCompat.toBundle());
    }

====================================================
從左邊進入動畫slide_left_in.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
    <translate
        android:duration="300"
        android:fromXDelta="-100.0%p"
        android:toXDelta="0.0" />
</set>

從左邊退出動畫slide_left_out.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
    <translate
        android:duration="300"
        android:fromXDelta="0.0"
        android:toXDelta="-100.0%p" />
</set>

====================================================
從底下進入動畫slide_bottom_in.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:interpolator="@android:anim/accelerate_decelerate_interpolator"
     android:shareInterpolator="true">
    <translate
        android:duration="300"
        android:fromYDelta="100%p"
        android:toYDelta="0.0" />
</set>

從底下退出動畫slide_bottom_out.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:interpolator="@android:anim/accelerate_decelerate_interpolator"
     android:shareInterpolator="true">
    <translate
        android:duration="300"
        android:fromYDelta="0.0"
        android:toYDelta="100%p" />
</set>

====================================================
若要對所有Activity的頁面跳轉設定統一的動畫，只需使用MyTheme主題即可：

 <!--統一頁面跳轉動畫-->
    <style name="ActivitySwitchAnimation">
        <item name="android:activityOpenEnterAnimation">@anim/slide_bottom_in</item>
        <item name="android:activityOpenExitAnimation">@anim/slide_bottom_out</item>
        <item name="android:activityCloseEnterAnimation">@anim/slide_bottom_in</item>
        <item name="android:activityCloseExitAnimation">@anim/slide_bottom_out</item>
    </style>

    <style name="MyTheme" parent="AppTheme">
        <item name="android:windowAnimationStyle">@style/ActivitySwitchAnimation</item>
    </style>
